I doubt that in my lifetime I will ever have to worry about Satan reading my mind, because I will probably never meet him. He can only be in one place at one time. He’s a creature, and creatures by definition are limited spatially and temporally. So Satan cannot be at more than one place at a time. He has all his little junior assistants, and he might send one of them to harass me and to tempt you and accuse you, but he’s going to save his time and energy for people of greater influence than me.
